WEAVING- SHUTTLE.

Application filed May 6, 1924. Serial No. 711,478.

To all whom it 02mg concern:

Be it known that I, Pmnirrn OoMnAU, a

citizen of the United States of America, residing'at New Bedford, in thecounty of Bristol and State of Massachusetts, have invented a certainnew and useful Improve ment in lVeaving Shuttles; and I do herebydeclare that the following is a full, clear, concise, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in weaving shuttles, having foran object to provide a novel and efficient form of thread guide forshuttles, whereby the thread carried thereupon can be quickly andconveniently directed to the eye thereof and brought to a position withrelation to said eye, whereat it may be passed or threaded through thesame in a time much less than that required for threading operationswith the now prevalent types or designs of shuttles.

It is likewise an object of the invention to provide a device of thecharacter mentioned which, in addition to facilitating the threading ofthe shuttle eye, will provide an effectual tensioning means for thethread, causing the same to be evenly removed from the bobbin.

Other objects of the invention will be in part obvious, and in partpointed out here-' inafter. V

In order that the invention and its mode of operation may be readilyunderstood by persons skilled in the art, I have in the accompanyingillustrative drawings, and in the detailed following description basedthereupon, set out one possible embodiment of the same.

In these drawing.

Figure 1 is a fragmentary side elevation of a shuttle equipped with theinvention;

Figure 2 is an enlarged fragmentary perspective view of such a shuttle;

Figure 3 is an enlarged fragmentary detail in section taken on the line3-3 of Figure 1;

Figure 4; is an enlarged fragmentary detail in section taken on the line4 4E of Figure 1; and,

Figure 5 is a reduced top view of the same.

Having more particular reference to the drawings, in connection withwhich like characters of reference will designate corresponding partsthroughout, 1 represents the shuttle proper having the usual pivotallymounted spindle 2 therein adapted to re ceive a bobbin such as indicatedat 3, upon the same. One portion of the shuttle 1 is chambered orrecessed as indicated at 4, such chambered portion 4: being disposedlongitudinally of the shuttle proper 1 as is clearly shown in theFigures 2 and 5, the outer portion thereof being enlarged as indicatedby the numeral 5, and having the lower portion thereof communicatingwith a longitudinally disposed reduced way (3. An eye 7 is received inan adjacent portion of the shuttle proper 1, transversely of the same,as indicated in the Figures 1 and 2 and is positioned adjacent to theinner end of said longitudinally disposed reduced way 6.

From the foregoing, it will be seen that a tortuous path ofcommunication is established as between the spindle and bobbin receivingchamber or pocket of the shuttle 1 and the eye 7, whereby the thread 8from said bobbin 3 may be passed into and through or threaded throughtheeye 7.

Vith a view towards providing effectual guide means for the thread 8from the bobbin 3 in order that the same may be directed to a positionadjacent to the eye 7 whereby to facilitate quick or convenientthreading of the latter, I provide a guide indicated in its entirety bythe numeral 9. a

This guide 9 consists of a single length of wire or similar pliable orbendable material, but which possesses sufilcient rigidity as to ensureits remaining in proper form subsequently to bending or shaping of thesame.

The guide 9, as will be noted upon reference to the Figures 2 and 5, isvdisposed longitudinally of the chamber 1, having its inner end bent atsubstantially right angles whereby to provide an anchoring arm orportion 10 adapted to be embedded in an adjacent portion of the bottomof the chamber 42. An arm 11 is bent diagonally clownwardly andrearwardly from the body portion of said guide 9 and as shown in theFigures 1 and 2, this arm is passed through a way 12 opening onto thatside .of the shuttle proper 1 receiving the eye 7, whereupon it isextended in substantial parallelism to said side of the shuttle proper 1and is outwardlybent and, substantially upon itself as indicated by thenumeral 13. A

portion of this outwardly bent part of the arm 11, as shown in theFigures 1 and 2,

is extended across the eye 7, whereupon the free end of the arm isformed with a right angularly disposed anchoring finger l l engaged orembedded in an adjacent portion of the side of the shuttle proper 1.

In this connection, it *isto bei noted that the forwardly disposedportion of the out- 'wardly bent part 13 is directed through the way oropening 12 to a point whereat the same registers or aligns with thereduced longitudinal way 6, the purpose of which will be subseq'i'ientlydescribed.

In order that the eye '7 andthat portion of the arm 11 adjacent thesamewill not interfere with free movement of the shuttle 1 during operationof the same,'I may and preferably do recess that side portion of saidshuttle receiving the same in the man ner as indicated by the numeral15, thus permitting the outer end or portion of the eye -7 and theoutwardly bent portion 13 of the arm 11 to be inset with respect to theside of the shuttle 1 receiving the same.

The eye 7 is preferably made of porcelain as is indicated upon thedrawings, having a thread receiving slot communicating at its lower endwith the inner end of the reduced longitudinal way (5. This way (3 alsolies horizontally of the bobbin as its outer end terminates at one sidethereof and its inner end communicates with the bottom of the verticallyand longitudinally extend ing recess 1. The medial portion of the wire 9forms a loop shaped'guide finger lying longitudinally within theenlarged por tion 5 of the recess't whereby the thread will be directedfrom'the recess a into the way '6, but this wire does not extend intotheway 6. Therefore, this wire 9 only forms a guide in so far as itpermits the making of a loop in the thread andguiding the latter fromthe recess'et to the way- 6, but the particular-configuration of thewalls of the recess& and the wayG, as shown, causes the thread to befinally threaded within the eye 7. V

The modus operandi of my improved shuttle is as follows:

To thread the eye 7, a portion of the thread 8 is removed from thebobbin3 and I is passed along one side of the guide 9as is indicated in theFigure 2, whereupon and then drawn through the reduced longitudinal way6 so that the same will be brought into the thread receiving groove orw'ay of the eye '7, it being borne in mind that the eye 7 communicateswith the adjacent end of said way 6 and in consequence, permits theready passing or threading of said thread through the eye 7. Dur ingthis threading operation, it will be seen that the guide 9 will serve asan offectual means for carrying the span of thread 8 forwardly and thendownwardly to a position adjacent the opening 12, whereupon, withpassage of the freeportion of said thread throitigh the opening 12, itmay be engaged and then drawn through the way 6 and threaded -withrespect to the eye 7.

By usage of my improved threading device, an operator is permitted toeffectually threadthe shuttle eye in a time much less than that requiredinthe threading operations of shuttles now prevalent in this art andfurthermore, it will be understood that the effort expended during sucha threading operation will be minimized.

Ma-nifestly, the construction shown is -capable of considerablemodification, and

'of the shuttle having a constricted longitudinal way extendingtherefrom, a shuttle eye positioned in said side of the shuttle havingits thread receiving recess communicating with said way,.and the threadguide finger formed of a single piece of material having one end thereofamrhored inthe guide chamberadjacent its point of communication with thebobbin chamber and disposed longitudinally of such guide chamber, theouter part of said finger being bent downwardlyand at angles upon itselfand disposedin that portion, of the .same opening transversely onto saidside of -the shuttle, the free end of the fingcr being disposedinsubstantial parallel relationship to an. adjacent portion of said sideof: the shuttle and arranged in proximity to the constrictedlongitudinal way and said shuttle eye.

In witness whereof I have hereunto set myhand; I

PHILIPPE COMEAU.
